Citric acid for cleaning

So I’ve found a couple of posts for cleaning probes but they are a bit dated and some of the links no longer work.

Would I cause problems or damage if I used citric acid powder mixed into ro water to clean my ph, conductivity, temperature and redox probes?
They probes are in my sump. They are starting to get a good build up of coralline algae and feather dusters.

You can easily clean the probes with citric acid. (powder with ro water)Then the probes must be recalibrated except for the temperature probe.
